Description

Die Erfindung bezieht sich auf die Ausgestaltung eines Körpers an einem Faden für einen Teebeutel, auf ein Verfahren zur maschinellen Befestigung eines Fadens an einem Körper aus einem textilen oder fasrigen Werkstoff, insbesondere an einem Etikett für einen Teebeutel sowie auf eine Vorrichtung zur maschinellen Befestigung eines Fadens an einem Körper nach den Oberbegriffen der Patentansprüche 1, 4 und 8.The invention relates to the configuration of a body on a thread for a tea bag, to a method for fixing a thread to a body of a textile or fibrous material, in particular to a label for a tea bag and to a device for fixing a thread mechanically on a body according to the preambles of claims 1, 4 and 8.

Es ist seit langem bekannt, Teebeutel mit einem Faden zu versehen und an dem freien Ende des Fadens ein Etikett anzubringen, auf dem beispielsweise Angaben über die Teesorte und den Teehersteller aufgedruckt sind. Solche Faden-Etikett-Verbindungen dienen auch dazu, den Teebeutel in einem mit heißem Wasser gefüllten Behälter zu halten und den Teebeutel nach der Teebrühzeit aus dem Heißwasserbad entfernen zu können, ohne dass der Benutzer dabei in Kontakt mit dem heißen Teewasser gelangt. Oftmals sind die Verbindungen zwischen Faden und Etikett mit Hilfe von zwei und mehr Knoten geschaffen, da der Faden mehrfach durch das Etikett hindurchgeführt ist, und zwar durch mindestens zwei Durchgangsöffnungen. Dies ist beispielsweise in den Druckschriften EP 0 691 268.A1 und EP 1 479 612 A1 beschrieben.It has long been known to provide tea bags with a thread and to attach at the free end of the thread a label on which, for example, information about the type of tea and the tea maker are printed. Such thread label compounds also serve to hold the tea bag in a container filled with hot water and to be able to remove the tea bag after Teebrühzeit from the hot water bath without the user gets in contact with the hot tea water. Often, the connections between the thread and the label are created by means of two or more knots, since the thread is passed several times through the label, through at least two through holes. This is for example in the publications EP 0 691 268 A1 and EP 1 479 612 A1 described.

Ferner können die Etiketten an dem Faden auch mittels einer Metallklammer befestigt sein.Furthermore, the labels can also be fastened to the thread by means of a metal clip.

Aus der US 2. 149, 713 A ist ein Teebeutel zu entnehmen, der aus zwei Flächengebilden aufgebaut ist, zwischen denen eine vorgegeben .Menge Tee eingefüllt ist. Die beiden Flachengebilde werden mittels eines Klebstoffes, der hitzebeständid ist, zusammengepresst. In einem Eckbereich des Teebeutels ist ein Faden angeknotet.From the US 2,149,713 A is to take a tea bag, which is composed of two fabrics, between which a given .Menge tea is filled. The two flat structures are pressed together by means of an adhesive that is heat-resistant. In a corner of the tea bag, a thread is knotted.

Nachteiligerweise ist aus dieser Druckschrift nicht_bekannt geworden, wie der jeweilige Knoten des Fadens an dem Teebeutel hergestellt wird, und zwar insbesondere ob die Herstellung des Knotens mit Hilfe von beweglichen maschinell befätigten Bauteilen erfölgt.Disadvantageously, it has not become known from this publication how the respective knot of the thread is produced on the teabag, in particular whether the manufacture of the knot is effected by means of movable machine-actuated components.

Es hat sich jedoch aufgrund von Kundenwünschen die Anforderung ergeben, das Etikett ohne Metallklammer an dem Faden zu befestigen, da die Metallklammer nicht kompostierbar oder der Kontakt zwischen Metallklammer und Teewasser nicht gewünscht ist. Des Weiteren ist nachteilig, dass die Metallklammern in Mikrowellen einen störenden Einfluss ausüben, durch die die Qualität des Teewassers vermindert ist. da es zu starker Überhitzung der Klammer oder auch zu Funkenüberschlägen kommen kann.However, due to customer requests, it has become necessary to attach the label to the thread without a metal clip, since the metal clip does not Compostable or the contact between metal clamp and tea water is not desired. Furthermore, it is disadvantageous that the metal brackets exert a disturbing influence in microwaves, through which the quality of the tea water is reduced. as it can lead to excessive overheating of the clip or even to flashovers.

Darüber hinaus nimmt die Metallklammer auf dem relativ klein bemessenen Etikett einen großen Raum ein, und zwar auf beiden Seiten des Etikettes, so dass die auf dem Etikett aufgedruckten Angaben im Bereich der Metallklammer unterbrochen und dadurch eingeschränkt sichtbar sind.In addition, the metal clip occupies a large space on the relatively small sized label, on both sides of the label, so that the information printed on the label in the metal clip area are interrupted and thus restrictedly visible.

Um die sich aus diesem Stand der Technik ergebenden Nachteile zu überwinden, ist eine Vorrichtung sowie ein Verfahren von der Patentanmelderin entwickelt worden, die als Europäische Patentanmeldung EP 2 366 628 unter Schutz gestellt sind.In order to overcome the disadvantages resulting from this prior art, a device and a method has been developed by the applicant, as European Patent Application EP 2 366 628 are under protection.

Dort wird mit Hilfe eines schmelz- und klebefähigen Körpers durch die Schlaufe des Fadens zunächst auf der Rückseite des Körpers eine Fixierung der Fadenschlaufe erreicht. Anschließend wird der schmelz- und klebefähige Körper mit Hilfe einer Heizeinrichtung aufgeschmolzen, so dass dieser eine feste Verbindung zwischen dem Etikett und dem Faden herstellt, so dass der Faden an dem Etikett fixiert ist.There is achieved by means of a meltable and adhesive body through the loop of the thread first on the back of the body fixation of the thread loop. Subsequently, the fusible and adhesive body is melted by means of a heater, so that it establishes a firm connection between the label and the thread, so that the thread is fixed to the label.

Als nachteilig hat sich bei diesem Verfahren bzw. für die Vorrichtung zur Durchführung des Verfahrens herausgestellt, dass die Heizeinrichtung in der Anschaffung äußerst kostenintensiv ist und zudem während des Betriebes Heizenergie benötigt.A disadvantage has been found in this method or for the apparatus for performing the method that the heater is extremely expensive to purchase and also requires heating energy during operation.

Darüber hinaus verlangt der Verbraucher und die Industrie eine Anordnung aus Teebeutel, Faden und Etikett, die vollständig biologisch recycelbar ist. Der schmelz- und klebefähige Körper besteht jedoch aus Kunststoff und anderen chemischen Bestandteilen, die biologisch nicht abbaubar sind. Auch wenn der schmelz- und klebefähige Körper einen relativ gering bemessenen Volumenanteil bezogen auf Teebeutel, Faden und Etikett aufweist, ist eine vollständig recycelbare Anordnung aus Faden, Etikett und Teebeutel anzustreben.In addition, the consumer and the industry require an arrangement of teabags, thread and label that is fully biologically recyclable. However, the fusible and stickable body is made of plastic and other chemical ingredients that are not biodegradable. Even if the meltable and adhesive body has a relatively small volume fraction relative to the tea bag, thread and label, a completely recyclable arrangement of thread, label and teabag is to be striven for.

Es ist daher Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung der eingangs genannten Gattungen zur Verfügung zu stellen, mittels denen eine zuverlässige Verbindung zwischen einem Faden und einem Körper, insbesondere einem Etikett für ein Teebeutel, herstellbar ist, ohne dass für die Verbindung zwischen dem Faden und dem Körper ein zusätzlicher nicht biologisch abbaubaren Verbindungskörper bzw. mehrere Knoten oder Fadendurchführungen notwendig ist bzw. sind.It is therefore an object of the invention to provide a method and an apparatus of the aforementioned types, by means of which a reliable connection between a thread and a body, in particular a label for a tea bag, can be produced without the need for the connection between the Thread and the body an additional non-biodegradable connecting body or more nodes or thread feedthroughs is necessary or are.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 hinsichtlich der Körperausgestaltung und des kennzeichnenden Teils von Patentanspruch 4 hinsichtlich des Verfahrensablaufes und durch die kennzeichnenden Merkmale von Patentanspruche 8 hinsichtlich der Vorrichtung gelöst.This object is achieved by the features of the characterizing part of claim 1 with respect to the body design and the characterizing part of claim 4 with respect to the procedure and by the characterizing features of claims 8 with respect to the device.

Weitere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous developments of the invention will become apparent from the dependent claims.

Dadurch, dass der Faden an dem Körper auf einer Seite derart verknotet ist, dass der Durchmesser des gebildeten Knotens größer bemessen ist als die Durchgangsöffnung, durch die der Faden durch den Körper geführt ist, ist der Körper an den Faden einseitig befestigt. Vorteilhafterweise sind für eine solche Befestigung keine zusätzlichen Hilfsmittel notwendig, so dass die Verbindung zwischen dem Körper, dem Faden und einem Teebeutel vollständig aus einem biologisch abbaubaren Werkstoff, beispielsweise Papier, Pappe oder einer Naturfaser, hergestellt werden kann.Characterized in that the thread is knotted on the body on one side such that the diameter of the knot formed is sized larger than the passage opening through which the thread is passed through the body, the body is attached to the thread on one side. Advantageously, no additional tools are necessary for such attachment, so that the connection between the body, the thread and a tea bag can be made entirely of a biodegradable material, such as paper, cardboard or a natural fiber.

Die maschinelle Verknotung des Fadens auf einer der Oberflächen des Körpers erfolgt mit Hilfe von lediglich zwei Maschinenteilen, nämlich einem Haltebügel und einem Greifer, durch die der Faden mittels linearer und rotatorischer Bewegungen in sich verknotet ist. Darüber hinaus wird für die Fadendurchführung lediglich eine Durchgangsöffnung benötigt, um den Faden durch den Körper zu führen und daran zu befestigen. Die Verknotung des Fadens erfolgt vorteilhafterweise ausschließlich auf einer Seite des Körpers.The machine knotting of the thread on one of the surfaces of the body takes place with the help of only two machine parts, namely a headband and a gripper, through which the thread is knotted by means of linear and rotary movements in itself. In addition, only one through hole is required for the thread passage to guide the thread through the body and to attach it. The knotting of the thread advantageously takes place exclusively on one side of the body.

Aufgrund der wenigen Maschinenteile, die notwendig sind, um die Verknotung des Fadens zu bewerkstelligen, reduzieren sich die Produktionskosten für die Anfertigung einer solchen Verknotungs-Vorrichtung erheblich. Zudem sind die Bewegungen der Greifer und des Haltebügels derart synchronisierbar, dass diese eindeutig definiert ablaufen können, um die Verknotung des Fadens zu erreichen.Due to the few machine parts that are necessary to accomplish the knotting of the thread, the production costs for production are reduced Such a knotting device considerably. In addition, the movements of the gripper and the retaining clip are synchronized so that they can run clearly defined to achieve the knotting of the thread.

In der Zeichnung ist der Verfahrensablauf für die Verknotung eines Fadens mit Hilfe einer Vorrichtung sowie eines der Maschinenbauteile der Vorrichtung und der fertig verknotete Faden an einem Körper dargestellt, die nachfolgend näher erläutert sind. Im Einzelnen zeigt:

Figur 1 ist zu entnehmen, dass ein Endlosfaden 5 an einem Körper 2 mittels einer Vorrichtung 1 maschinell befestigt werden soll. Die Vorrichtung 1 besteht im Wesentlichen aus einem Haltebügel 11 und einem Greifer 13, der zwei Spreizarme 14 und 15 aufweist. Der Haltebügel 11 und der Greifer 13 sind relativ zueinander in horizontaler und/oder vertikaler Richtung an der Vorrichtung 1 beweglich gelagert; deren Bewegungen zueinander sind in Abhängigkeit von der Position des Fadens 5 synchronisiert - wie dies nachfolgend erläutert ist. FIG. 1 It can be seen that an endless yarn 5 is to be mechanically fixed to a body 2 by means of a device 1. The device 1 consists essentially of a headband 11 and a gripper 13, which has two spreading arms 14 and 15. The bracket 11 and the gripper 13 are mounted relative to each other in the horizontal and / or vertical direction on the device 1 movable; their movements to each other are synchronized depending on the position of the thread 5 - as explained below.

Im Ausgangszustand ist der Faden 5 durch eine Öse 8 einer Nadel 7 hindurchgeführt und die Nadel 7 ist im Bereich einer ersten Oberfläche 3 eines Körpers 2 angeordnet. Der Körper 2 besteht aus einem textilen oder faserigen Werkstoff, vorzugsweise aus Papier Pappe oder einer Naturfaser, und dient als Etikett für einen Teebeutel. Die Spitze der Nadel 7 ist in Richtung des Körpers 2 ausgerichtet, um diesen gemeinsam mit dem Faden 7 zu durchdringen.In the initial state, the thread 5 is passed through an eyelet 8 of a needle 7 and the needle 7 is arranged in the region of a first surface 3 of a body 2. The body 2 is made of a textile or fibrous material, preferably paper paperboard or a natural fiber, and serves as a label for a tea bag. The tip of the needle 7 is aligned in the direction of the body 2 in order to penetrate this together with the thread 7.

In Figur 2 und 3 ist gezeigt, dass die Nadel 7 von der ersten Oberfläche 3 des Körpers 2 durch diesen hindurch zu einer zweiten gegenüberliegenden Oberfläche 4 des Körpers 2 geführt ist und dabei den Faden 5 zweiadrig mitzieht, so dass im Bereich der zweiten Oberfläche 4, in deren Bereich der der Haltebügel 11 und der Greifer 13 angeordnet sind, eine zweiadrige Schlaufe 21 des Fadens 5 gebildet ist, sobald die Nadel 7 wenige Millimeter zurückgezogen ist. Mit Hilfe der Nadel 7 wird folglich in den Körper 2 eine Durchgangsöffnung 10 eingearbeitet, durch die der Faden 5 zweiadrig verläuft.In FIGS. 2 and 3 is shown that the needle 7 is guided from the first surface 3 of the body 2 therethrough to a second opposite surface 4 of the body 2, while the thread 5 zweiadrig along, so that in the region of the second surface 4, in the region of the the retaining bracket 11 and the gripper 13 are arranged, a two-wire loop 21 of the thread 5 is formed as soon as the needle 7 is retracted a few millimeters. With the help of the needle 7, a passage opening 10 is thus incorporated into the body 2, through which the thread 5 is two-wire.

Es ist auch denkbar, dass die Nadel 7 durch den Greifer 13 oder einen Haken ersetzt ist, die oder der von der zweiten Oberfläche 4 des Körpers 2 in Richtung der ersten Oberfläche 3 durch die bereits vorhandene Durchgangsöffnung 10 des Körper 2 bewegt ist, um dort den Faden 5 zu fassen und durch die bereits vorhandene Durchgangsöffnung 10 hindurchzuziehen.It is also conceivable that the needle 7 is replaced by the gripper 13 or a hook which is moved from the second surface 4 of the body 2 in the direction of the first surface 3 through the already existing through hole 10 of the body 2 to there To grasp the thread 5 and pull through the existing through hole 10.

In Figur 4 ist gezeigt, dass durch eine auf die Schlaufe 21 ausgerichtete Bewegung des Haltebügels 11 die Schlaufe 21 am freien Ende des Haltebügels 21, an den eine vollständig oder bereichsweise umlaufende Nut 12 eingearbeitet ist, aufgenommen wird. Beim Zurückziehen der Nadel 7 wird demnach die Schlaufe 21 von dem Haltebügel 11 aufgenommen, in der Nut 12 abgelegt und dort gehalten, so dass diese im Raum und im Bereich der zweiten Oberfläche 4 fixiert ist.In FIG. 4 It is shown that by a directed to the loop 21 movement of the retaining clip 11, the loop 21 at the free end of the retaining clip 21, to which a completely or partially circumferential groove 12 is incorporated, is added. When retracting the needle 7, therefore, the loop 21 is received by the headband 11, stored in the groove 12 and held there, so that it is fixed in space and in the region of the second surface 4.

Der Haltebügel 11 befindet sich dabei auf einer vorgegebenen Seite des Greifers 13 und führt anschließend, wie dies in Figur 5 dargestellt ist, die Schlaufe 21 um die beiden Spreizarme 14 und 15 des Greifers 13, so dass eine etwa L- oder U-förmige Umschlingung an dem Greifer 13 entsteht. Es ist auch denkbar, dass der Greifer 13 relativ zu dem Haltebügel 11 und der Schlaufe 21, wie vorstehend erläutert, bewegt wird. Bei dieser Bewegung handelt es sich um eine lineare Bewegung; entscheidend ist, dass eine Relativbewegung zwischen dem Haltebügel 11 und dem Greifer 13 vorliegt, um die L- oder U-förmige Umschlingung 22 um den Greifer 13 zu schaffen.The headband 11 is located on a predetermined side of the gripper 13 and then performs, as in FIG. 5 is shown, the loop 21 to the two spreading arms 14 and 15 of the gripper 13, so that an approximately L- or U-shaped looping on the gripper 13 is formed. It is also conceivable that the gripper 13 is moved relative to the retaining bracket 11 and the loop 21, as explained above. This movement is a linear movement; It is crucial that a relative movement between the headband 11 and the gripper 13 is present to provide the L or U-shaped loop 22 around the gripper 13.

Den Figuren 6, 7 und 8 ist zu entnehmen, dass der Greifer 13, dessen Spreizarme 14 und 15 geschlossen sind, um die eigene Längsachse rotiert. Der Greifer 13 dreht sich mindestens einmal vollständig, also um 360°, um die eigene Achse, um zwischen dem von dem Haltebügel 11 und der an dem Greifer 13 anliegenden L- oder U-förmigen Umschlingung 22 einen oder mehrere Achter-Wicklungen 23 auszubilden. Je mehr solcher Achter-Wicklungen 23 entstehen, desto größer wird anschließend der Durchmesser eines fertigen Fadenknotens 26.The FIGS. 6 . 7 and 8 It can be seen that the gripper 13, the spreading arms 14 and 15 are closed, rotates about its own longitudinal axis. The gripper 13 rotates at least once completely, so by 360 °, about its own axis to form one or more figure-of-eight windings 23 between the voltage applied by the bracket 11 and the voltage applied to the gripper 13 L or U-shaped loop 22. The more such eight-turns 23 are produced, the larger the diameter of a finished thread knot 26 becomes.

Zur besseren Aufnahme der Schlaufe 21 wird der Greifer 13 nach Fertigung der Achter- Wicklung 23 derart verdreht, dass die beiden Spreizarme 14 und 15 parallel zu dem Haltebügel 11 und seitlich versetzt zu diesem ausgerichtet sind.For better reception of the loop 21 of the gripper 13 is rotated after manufacture of the aft winding 23 such that the two spreading arms 14 and 15 are aligned parallel to the headband 11 and offset laterally to this.

In Figur 9 ist zu entnehmen, dass der Haltebügel 11 parallel zu dem Greifer 13 bewegt ist und dass die beiden Spreizarme 14 und 15 des Greifers 13 geöffnet sind. Beim Zurückfahren des Haltebügels 11 wird die an diesem aufgenommene Schlaufe 21 zwischen den beiden geöffneten Spreizarmen 14 und 15 eingefädelt, so dass ein einadriger Fadenteil 24 zwischen den Spreizarmen 14 und 15 verläuft. Die Aufnahme dieses Fadenteils 24 wird im Wesentlichen dadurch bewirkt, dass der Greifer 13 um die eigene Längsachse um 90° oder mehr Grad gedreht ist und dabei das einadrige Fadenteil 24 aufgreift, wie dies in Figur 10 abgebildet ist.In FIG. 9 It can be seen that the headband 11 is moved parallel to the gripper 13 and that the two spreading arms 14 and 15 of the gripper 13 are opened. When retracting the retaining clip 11, the loop 21 received thereon is threaded between the two opened spreader arms 14 and 15 so that a single-stranded thread part 24 extends between the spreader arms 14 and 15. The reception of this thread part 24 is essentially brought about by the gripper 13 being rotated about its own longitudinal axis by 90 ° or more degrees, thereby picking up the single-stranded thread part 24, as shown in FIG FIG. 10 is shown.

Nachfolgend werden die Spreizarme 14 und 15 gemäß Figur 11 geschlossen, so dass das einadrige Fadenteil 24 in einer von den Spreizarmen 14 und 15 eingeschlossenen Öse 18 gehalten ist. Die Spreizarme 14 und 15 weisen zur verbesserten Aufnahme des Fadenteils 24 eine aufeinander zuweisende dreieckförmige Querschnittskontur 19 auf, durch die das Greifen des Fadenteils 24 sowie die Befestigung des Fadenteils 24 in der Öse 18 verbessert zu bewerkstelligen ist.Subsequently, the spreading arms 14 and 15 according to FIG. 11 closed, so that the one-wire thread part 24 is held in an enclosed by the Spreizarmen 14 and 15 eyelet 18. The spreader arms 14 and 15 have for improved recording of the thread portion 24 a successive attributed triangular cross-sectional contour 19 through which the gripping of the thread portion 24 and the attachment of the thread portion 24 in the eyelet 18 to accomplish improved.

Aus Figur 12 ist ersichtlich, dass die Schlaufe 21 von dem Haltebügel 11 gelöst ist, in dem der Haltebügel 11 aus der von der Schlaufe 21 gebildeten Ebene hinausgezogen ist. Folglich ist die Schlaufe 21 von dem Haltebügel 11 freigegeben.Out FIG. 12 It can be seen that the loop 21 is released from the headband 11, in which the headband 11 is pulled out of the plane formed by the loop 21. Consequently, the loop 21 is released from the headband 11.

Durch Ziehen des Fadens 5 aus deren aus dem Körper 2 herauslaufenden Fadenenden 6 auf der ersten Oberfläche 3 des Körpers 2 wird, wie in Figur 13 dargestellt, die L- oder U-förmige Umschlingung 22 über die beiden Spreizarme 14 und 15 des Greifers 13 gezogen; der Fadenteil 24 ist dabei fest in der Öse 18 gehalten, so dass sich die bislang hergestellte Verknotung nicht aufwickelt. Die Bewegung der L- oder U-förmigen Umschlingung 22 wird solange fortgesetzt, bis diese im Bereich der zweiten Oberfläche 4 des Körpers 2 angekommen ist. Dies ist Figur 14 zu entnehmen. Sobald dieser Zustand erreicht ist, können die beiden Spreizarme 14 und 15 gemäß Figur 15 geöffnet und der Greifer 13 kann aus dem Fadenteil 24 gezogen werden, so dass dieser gemäß Figur 16 freigegeben ist. Alternativ kann auch das Etikett mit Knoten (am Faden) aus dem Greifer gezogen werden.By pulling the thread 5 from its outgoing from the body 2 yarn ends 6 on the first surface 3 of the body 2, as in FIG. 13 shown, the L or U-shaped loop 22 pulled over the two spreading arms 14 and 15 of the gripper 13; the thread part 24 is firmly held in the eyelet 18, so that the knot made so far does not wrap up. The movement of the L or U-shaped loop 22 is continued until it has arrived in the region of the second surface 4 of the body 2. This is FIG. 14 refer to. As soon as this state is reached, the two spreading arms 14 and 15 can according to FIG. 15 opened and the gripper 13 can be pulled out of the thread part 24 so that this according to FIG. 16 is released. Alternatively, the label with knots (on the thread) can be pulled out of the gripper.

In Figur 17 ist der Fadenknoten 26 an der zweiten Oberfläche 4 des Körpers 2 gezeigt, dessen Durchmesser wesentlich größer bemessen ist als der Durchmesser der Durchgangsöffnung 10, so dass aufgrund des vorhandenen Fadenknotens 26 der Faden 7 an dem Körper 2 befestigt ist.In FIG. 17 the thread knot 26 is shown on the second surface 4 of the body 2, whose diameter is dimensioned substantially larger than the diameter of the through hole 10, so that due to the existing thread knot 26 of the thread 7 is fixed to the body 2.

In Figur 18 ist der Greifer 13 mit seinen beiden Spreizarmen 14 und 15 abgebildet, die ineinander beweglich gelagert sind.In FIG. 18 the gripper 13 is shown with its two spreader arms 14 and 15, which are movably mounted.
